Convert warnings to info as not all platforms may
have all the thresholds and sensors enabled.

This seems overly generalized to me. Shouldn't we be checking in a more
fine-grained way for the absence of thresholds and/or sensors?

Otherwise, how are going to make the difference between the sensor not
being enabled or the device tree just missing the information?

The sensor being enabled or not is controlled by device tree, if the dts
have the corresponding nodes, then the sensors should be enabled. And
the thresholds for sensor are not necessary, so I think we just need to
print out them.
BTW, in my patch 1/4, I should print out the sensor name if the sensor
not enabled and register failed.
Will update it.
